The system approach developed by L-ACOUSTICS
®
consists in offering a global solution that guarantee the highest and
most predictable level of performance at any step of loudspeaker system deployment: modeling, installation and
operation. A complete L-ACOUSTICS
®
system includes enclosures, amplified controllers, cables, rigging system and
software applications.
The main components of an ARCS
®
WIDE SYSTEM or ARCS
®
FOCUS SYSTEM are the following:
2.1 Loudspeaker enclosures
ARCS
®
WIDE Full-range (55Hz – 20kHz), 2-way passive, constant curvature WST
®
line source, 90° x 30°
ARCS
®
FOCUS Full-range (55Hz – 20kHz), 2-way passive, constant curvature WST
®
line source, 90° x 15°
SB18m High power subwoofer (down to 32Hz)
Loudspeaker system design
Sound design aspects are beyond the scope of this document. However, the various applications of the
system will be based on the operating modes presented in this document.
2.2 Powering and driving system
LA4 or LA8 Amplified controllers with DSP library and networking capabilities
